Stone has returned to London. Both the UK and the US are in a state of unrest and ever more extreme politicians are looking to take advantage of an unstable world. Their motives are unclear. But their threat is real. Who are they really working for? Backed into a corner by a man he knows he cannot trust, ex-deniable operator Nick Stone strikes a devil's bargain. In exchange for his own safety, he is charged with locating someone who doesn't want to be found, currently hiding out in one of the remotest corners in the UK - and this time Stone is not operating alone. But he and his team don't find just anyone: they find a world-class hacker whose work might threaten the stability of the western world as we know it. Before Stone finally sees which way to turn, the choice is ripped out of his hands. Most people might think of home as safety, but Nick Stone isn't most people. For him and his team, it's just another place to get caught in the line of fire...
